Guo Juan lesson: City League and Boston Spring Open games

I had a lesson with Guo Juan yesterday, in which she reviewed my City League game with Audrey and my games from the Boston Spring Open.

In my game with Audrey, Guo Juan praised my initiative.  My two biggest problems were misreading a life-and-death situation (which led to my using the wrong strategy in my game) and some poor choices in the end game.  Here it is with my notes on what Guo Juan told me:

In my tournament game with Andrew, we both played some slow moves.  I did eventually play the right move to split White's groups, but I didn't play it right away, as I should have.  There were several basic things I did wrong:  I played a non-threat in the ko (and missed the real ko threat that was available to me); I captured some stones in the wrong way; and I failed to block White when White pushed through between my groups.  Guo Juan also gave me a link to one of her Lunch Special lectures in response to a question I asked about a corner situation.  (As is often the case, we were wrong in our post-game analysis.)

In my game with Deren, I also had some slow moves, but I learned a key idea in dealing with the 3-3 point.  When I approached the 3-3, Deren played a keima away from the 3-3.  I (bumbling around, with no idea of how to handle this) approached his upper left corner.  This was a mistake because when White pincers my approach stone (the one approaching the 3-3), I have no where to go (this is very different from when my opponent has a 4-4 or even a 3-4 stone in the corner).  So I should just calmly defend my approaching stone.  Then I can either get a nice approach against his 4-4 in the upper left, or a really nice move against the keima on the bottom.
